So I tried to single-handedly replace a slab of sidewalk last week.
Near killed my po' self, mixing and pouring, etc. Was so worried
about thunderstorms etc, I forgot to cut/set the expansion joints.
Forced 'em in as the 'crete was being finished. They stick up
as much as an inch above slab-level.

How do you cut this stuff? It is Quikrete 1/2 In. x 4 In. x 5 Ft.
Expansion Joint per Homey-Flogging-Depot:

Sez it is made from resilient cane fiber. Looks like cardboard
soaked in asphalt gunk. Tried cutting with utility knife, it sorta
shreds.

Best case would be if I could pull 'em out without making a hideous mess.
Then
I could cut some wood joints to replace 'em. But they don't seem to wanna
come out.

Mea Culpa: I blew this part of the job. Any help much appreciated.

Uh, did you read the "no drip caulk gun" thread? Apparently the checkout
persons at HD are now telling you how to do things. I'm sure they'd be
able to guide you.

How about a router?
